Specification of Letters Patent.

To all 1,071,071?, 7225 may concern:

Beit known that I, EDUARD URBAN, a subject of the Emperor of Austria-Hungary, and a resident of Blowitz, near Pilsen, Austria- Hungary, have invented certain new yand useful Improvements in Engines with Revolving Cylinders, of which the following is a specification.

The invention relates to improvements in engines with revolving cylinders whose axes lie in a plane vertical to the shaft; and the essential feature of the same consists therein that the fresh steam streaming into the cylinders couples, in the first place, the pistons with the flat walls of the fixed casing surrounding the cylinders, whereby an abutment for the movement of the cylinders is formed, whereupon this coupling on the steam streaming off into the condenser is autom atically disconnected. This arrangement allows of a simple transmission of the movement upon the shaft upon which Iis keyed a rim connected with the cylinders, so that by a repetition of the above-described process there is attained in each cylinder an uninterrupted rotation of the shaft.

In the drawings is represented in Figure 1 a vertical section through the engine on the line X X of Fig. 2; in Fig. 2, a horizontal section on the line Y Y of Fig. 1 5 in Fig. 3, a section on the line Z Z of Fig. 1 and in Fig. 4, a view of the distributing device, partly in section.

Similar numerals refer to similar' parts throughout the several views.

Upon theshaft 1 is keyed a cast-iron wheel 2, closed off by two covering-plates 3 4 and in which the driving-cylinders are fastened. The steam streams through the socket 5 into the steam-room 6, in which it is distributed by two disks 7 8, of which each one has as many openings as there are driving-cylinders, Fig. 4. The disk 8 is rigidly connected to the shaft 1, whereas the disk 7 is loose and can be turned by means of a crank 9 for the purpose of increasing or reducing the feed by a corresponding adjustment of the openings of both disks.

In each cylinder is a piston 10, Figs. 2 and 3, whose piston-rod 11 is guided in a tube 12 and rests against two keys 13 14, which are slidably journaled in a tube 12, which forms a right 'angle with the tube 12 and is connected with the same. If now the steam enters through the openings of the cover 3 into the cylinder, the piston 10 travels a short distance until it strikes with its flat surface against the end of the tube 12. The end of the piston-rod 11 thereby drives the keys 13 and 14 asunder and presses them against the upper and lower wall of the casing 15 16, whereby the piston becomes fixed by the tube 12. As, however, the steam continues to act, but the piston cannot move, the cylinder is moved backward, and thereby at the same time the wheel 2, which is rigidly united with it, rotates the shaft. During the movement of the cylinder the spring 17 is compressed, which after they steam has been blown out into the condenser 18 through the opening provided in the cover 4 brings back the piston 10 into its original position. This process is repeated in each of the driving-cylinders, by which an uninterrupted rotary movement of the shaft is attained. Instead of steam any other driving medium may be used for driving the engine.

What I claim as my invention, and desire to secure by United States Letters Patent, is-

In an engine with revolving cylinders whose aXes lie in a plane vertically to the shaft, the combination of a tube 12 guiding the'piston-rod 11 a tube 12, keys 13, 14 and oasings 3, 4, said keys adapted to be pressed against the fixed Walls 15, 16 and thus preventing a further movement of the piston 10 so that the driving medium streams to the cylinders and to the casing 3 ,4, substantially as described and shown and for the purpose Set forth.

In testimony whereof I have signed my name-to this specification in the presence of two subscribing witnesses.

EDUARD URBAN.
